| introduction | mepline is a plant growth regulator, which can inhibit plant elongation, slow down its growth and increase chlorophyll synthesis. it needs to be used many times in cotton growth. It is very helpful to enhance cotton stress resistance, increase cotton yield and improve cotton quality. |
| use | 1. control the upper and lower promotion, and promote the lower root system of cotton seedlings, especially the growth of fibrous roots. 2. Enhance the synthesis of chlorophyll, make the leaf color of cotton seedlings deep and improve photosynthesis. 3. Increase the stress resistance of cotton seedlings (I. e. enhance the physique of cotton seedlings). Only when the physique is good and strong can it better resist the influence of adverse weather environment on cotton growth. 4. Generally speaking, the newly unearthed cotton seedlings are lighter in color and generally yellow-green fields. Thrips and aphids will occur more seriously because they are sensitive to color during migration, especially yellow-green is very attractive to them. At the same time, the seedlings are very tender and delicious to them. Therefore, it is suggested that chemical control and pest prevention can be carried out at the same time, at the same time of chemical control, fungicides and pesticides are added to achieve the purpose of disease prevention and insecticidal. Plant growth inhibitor can inhibit plant cell and internode elongation. It has high activity on cotton, wheat, tomato and grape. It can control the growth of cotton, has a significant inhibitory effect on the height of the cotton plant and the length of the fruit branches, and makes the plant type tight and rebellious, sealing the line late, and reducing the shedding of the middle and lower cotton peaches. For cotton with vigorous growth, mepiperium 0.75g/100 m2 is sprayed with 11.3~15kg of water when the buds are full to the beginning of flowering, and the effective period is up to 25d, which can generally increase the yield by 10% ~ 20%. Tomato is sprayed with 100mg/L mepiperium twice before seedling transplanting and 6kg/100 m2 of liquid medicine, which can effectively control axillary buds, increase early flower volume, promote early fruit setting, reduce flower drop and fruit drop, and increase yield by more than 20%. Spraying 25~150mg/L liquid medicine on the leaves of apples can increase calcium ions and make the kernel smaller. After spraying citrus with 25~100mg/L liquid medicine, the fruit can be precocious and the pulp can be increased. Used in ornamental plants can inhibit the overgrowth of plants, make plants firm, resist lodging and improve color. as a plant growth regulator, it can promote plant development, bloom in advance, prevent shedding and increase yield as a plant growth regulator, it can enhance chlorophyll synthesis and inhibit the elongation of main stems and fruit branches helper is a new type of plant growth regulator, which can be used in a variety of crops and exert a variety of effects. It is widely used in cotton, which can effectively prevent cotton from growing wildly, control the compact plant type, reduce bell drop, promote maturity, and increase cotton production. In addition, Zhuangsu can be used in winter wheat to prevent lodging; it can be used in apples to increase calcium ion absorption and reduce bitterness; it can be used in oranges to increase sugar content; Zhuangsu is a plant growth regulator developed in the 70 s The most popular variety. |
| toxicity | acute oral LD50 in rats is 1490 mg/kg, and that in mice is 428 mg/kg. The acute percutaneous LD50 in rats was 7800mg/kg, and the acute inhalation of LC50 in rats was> 3.2mg/L(7h). It has a stimulating effect on the skin and eyes. For blue gill fish LC50>250mg/L, trout LC50 is 750mg/L. No obvious toxicity to bees and birds. |
| Production method | Pyridine is hydrogenated under high pressure under an aluminum-nickel alloy catalyst to produce hexahydropyridine (piperidine), and then react with formaldehyde and formic acid to obtain N-methyl piperidine, which is further pressurized with methyl chloride to prepare the aid. According to GB 9555-88, the original drug of the aid element is white or yellowish crystals, and the content of the active ingredient is ≥ 98.0%, and the first grade is ≥ 96.0%. The aid is processed into 25g/L ultra-low volume dosage form or 42g/L, 50g/L and 460g/L aqua. Raw material consumption quota: piperidine (converted into 100%)550kg/t, methyl chloride (converted into 100%)760kg/t. preparation method pyridine under the action of aluminum nickel catalyst, high pressure hydrogenation to produce hexahydropyridine, namely piperidine. Piperidine is methylated (methylating agent using formaldehyde and other reagents or methyl chloride) to make N-methyl piperidine. Under pressurized conditions, N-methylpiperidine undergoes onium salination reaction with methyl chloride to obtain mepiperium. Preparation method ii |
